Ported from JB 4.3
Based on hybrid (Aaron) and Halo (Jesus) implementation
Fix for launch app in floating mode from recents

Change-Id: I216b02a60cd46b7fef49e04fe090169c4703bcb6
Keep app when opening floating window from recents panel

Start activity asynchronously by appending it to system's
message queue to let RecentsPanelView cleanly execute
dismissAndGoBack before the floating window gets started.
